3. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 3 Charter The purpose of Focus Group 4 is to provide recommendations to the Council that, when implemented, will facilitate and assure interoperability of public data networks. The duties of the Focus Group 4 will be to prepare studies, reports, and recommendations for assuring data network interoperability within the parameters set forth in the NRIC V Charter. Focus Group 4 will determine what levels of interoperability are needed. Focus Group 4 will also monitor future developments to ensure that interoperability is not at risk. Focus Group 4 will make recommendations with respect to interoperability issues that may arise from convergence and digital packet networks. Focus Group 4 may also make recommendations with respect to such additional interoperability issues as the Commission may specify.

6. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 6 Carrier Interconnection / Peering Issue We have had discussions on SP interconnection and peering at all three meetings Consensus to publish a short statement encouraging service providers to publish their criteria for peering Goal is to foster transparency Cover letter and statement are attached Consensus to produce longer paper discussing interconnection issue Outline is attached

7. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 7 To: James Crowe The NRIC V Interoperability Focus Group (Focus Group 4) - has developed a consensus recommendation that it would like to place before the Network Reliability and Interoperability Council for consideration at its next meeting on June 26. The recommendation and statement, which are attached, request that the Council encourage Internet service providers, and especially the large "backbone" Internet providers that comprise the core of the modern Internet, to consider, consistent with their business practices, publication of their criteria for peering. More specifically, Focus Group 4 believes that this action will promote transparency and facilitate interoperability, especially with respect to new Internet service providers. Accordingly, we respectfully request that you place this recommendation before the Council at its next meeting and, if it is adopted, that the Council publish this recommendation. Sincerely, Scott Bradner, Ross Callon (co-chairs)

8. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 8 NRIC Encourages Publication of Peering Criteria to Promote Transparency Because no one provider directly connects a plurality of sites within the Internet, interconnection between providers is necessary. The form of interconnection known as "peering", in which Internet providers agree to exchange traffic for their respective customers but not for third parties, is commonly deployed and widely accepted. Internet providers do not and can not peer with all other Internet providers. They make conscious decisions as to which providers they will peer with, and under what business terms. In the United States, the decision to peer, or to decline to peer, is driven by market forces, rather than by government regulation. Moreover, there is no legal obligation to disclose these decisions or these terms. (continued...)

9. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 9 Over the past year, several of the largest Internet providers in the United States have voluntarily chosen to openly publish the basis on which they decide with whom they will peer. In the opinion of NRIC V, this has been a positive development, both for U.S. industry and for the global Internet community. It has significantly enhanced transparency of process in the industry. NRIC V encourages other Internet providers, and especially the large "backbone" Internet providers that comprise the core of the modern Internet, to consider, consistent with their business practices, publication of their criteria for peering.

12. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 12 Cooperation with 2.A2 Focus Group 2, working group 2.A2, has produced best practices for reliability in data networks Karl Rauscher gave a general overview to FG4 3/2001 FG4 went through BPs one-by-one at meeting 5/2001 Results have been written up, distributed to FG4, and updated based on comments received Next step: Relay to 2.A2

13. NRIC V Focus Group 4, Interoperability 1/6/2016 Ross Callon 13 Testing FG4 has had two discussions on testing Presentation by D.Currie, R.Parker, and R.Neumann, 3/2001 General discussion, 5/2001 Strong agreement on the importance of testing Agreement: There are many valid forms of testing There are many organizations involved in testing (including vendors and service providers) FG4 is reluctant to endorse any particular test group FG4 will produce a short draft summarizing conclusions to date For discussion at next FG4 meeting
